In the photoluminescence (PL) spectra, we observe the strong evidence that the band gap emission enhancement can be as high as 30 times. In the second part, the NiO-Cu¬¬2O superlattices (SLs) and Cu nanotubes were grown based on AAO membranes. We demonstrate the quantum confinement effect in NiO-Cu2O SLs. Finally, we attempt to transform the Cu nanotubes into Cu2O cactus shape nanotubes by using the combination of AAO template and hotplate methods.Contents Chapter 1 1 Introduction 1 References: 4 Chapter 2 5 Theoretical Background 5 2.1 Band gap structure 5 2.2 Recombination Processes 8 2.3 Photoluminescence (PL) 11 2.3.1 Introduction 11 2.3.2 Experiment Setup 12 2.4 Fluorescence resonance energy transfer (FRET)[3-4] 13 2.4.1 The basic requirements for the observation of FRET as follows. 13 2.5 Scanning Electron Microscopy [5] 15 2.6 Quantum Confinement Effect 17 2.7 Superlattice 19 Reference 21 Chapter 3 22 Enhancement of the band gap emission of ZnO nanorods by the assistance of CdSe/ZnS quantum dots 22 3.1 Introduction 22 3.1 Sample Preparation 25 3.3 Results and Discussion 29 Reference : 37 Chapter 4 39 4.1 Introduction 39 4.2 Copper oxide superlattices 40 4.2.1 Sample Preparation 40 4.2.2 Results and Discussion 42 4.3 Copper Oxide nanotubes 46 4.3.1 Motivation 46 4.3.1 Results and Discussion 48 Reference : 51 Chapter 5 53 Conclusions 53en-US氧化鋅量子點硒化鎘增強光致螢光光譜ZnOAAOPLCdSethesis
